Sediment Mapping and Analysis Project from Foster Lake Management

Foster Lake Management recently completed a mapping project for a home owners association in North Carolina.  The inlet area of the lake is suffering from sediment buildup. The overall goals of the lake mapping project involved surveying the depths of the entire lake, collecting sediment depth samples, calculating the amount of sediment currently in the inlet area and creating a dredge plan for a minimum water depth of 3 feet.   Foster Lake Management collected water depths over the entire lake and fluffy sediment levels for the inlet areas.  The Mapping Network then generated detailed hydrographic maps, 3D models, and sediment volume maps for the inlet area.  The HOA is now in the process of selecting bids for the removal of sediment to attain the 3 foot minimum depth.

Here at The Mapping Network, we specialize in accurately mapping bodies of water, calculating the water volume, collecting sediment depth samples at critical areas and monitoring the distribution of sediment over time.  We have a nationwide group of professionals specializing in all facets of lake management.

The bottom line – This powerful information allows for smart management and planning decisions and will serve as a baseline for future projects.  A great value! 

In the maps above, the HOA needed the depths of the cove to be a minimum of 3 foot for boat access. Mapping Network located the areas where the current depth was less than 3 feet, which was the dredging zone.  The Mapping Network calculated the dredging area and volume. The current lake bathymetry (left) and the post-dredge contours (middle) are shown in blue shading. A cut-fill model (right) shows areas of cut needed to reach the goal.
